Although not officially announced by the promotion, UFC on FOX 2 is expected to take place Jan. 28 at United Center in Chicago, Ill.

Einemo’s return comes three months after he and two teammates from Netherlands-based MMA team Golden Glory were cut from their UFC and Strikeforce contracts not long after UFC parent company Zuffa, LLC released then-Strikeforce champion Alistair Overeem.

As MMAjunkie.com earlier reported, UFC president Dana White said the cuts reflected a rift over payment of Golden Glory fighters. The team wanted fighter payments routed through them as opposed to direct payments per UFC policy, and until the team agreed to the policy, no Golden Glory fighters would fight in the UFC.

Soon, Golden Glory head Bas Boon said he had no problem with the UFC’s demand and expressed hope that the two sides could come back to the negotiating table. In September, officials announced the signing of Overeem to the UFC for a fight with Brock Lesnar at UFC 141, and Boon said Einemo would return to the octagon as well.

Einemo, a former ADCC champ, made his UFC debut at UFC 131 against fellow newcomer Dave Herman. In a back-and-forth bout, Herman won a second-round TKO, but the two were awarded an additional $70,000 each for “Fight of the Night” honors.

The bout was Einemo’s first in five years. He once appeared in the now-defunct PRIDE, where he lost a decision to Fabricio Werdum.

Russow has had plenty of layoffs, as well. The Chicago cop hasn’t fought since March, when he earned a second-round TKO over heavyweight prospect Jon Madsen. He was scheduled to fight Herman at UFC 136, but the bout was scratched when Herman failed a pre-fight drug test and was denied a license to fight.

Prior to his win over Madsen, Russow earned what many believed to be one of the best comeback wins in UFC history. Taking on Todd Duffee at UFC 114, he took a beating for two-plus rounds before landing a straight right hand that sent the red-hot prospect to the mat.

As the UFC 189 tour made its last stop in Dublin, featherweight champ Jose Aldo was met with a torrent of abuse from the Irish fans. It might have been unpleasant, but it might also have been just what he needed.
